AWS A 5.5: E 8018 - W2 |
Description |
A heavy coated basic iron powder type low hydrogen electrode for welding of weathering steels, medium and high tensile steels and joining them to mild and other structural steels. The electrode is having very good operating characteristics like smooth and steady arc, slag detachability. The electrode can be used easily in positions. Weld deposit is of high radiographic soundness. |
Application |
Joining of weathering steels of grades IRS M-41 and IRS M-42, ASTM A242, A588, Corten A& B and equivalent grades |
